MGT9212HR-W25B Protechnic 92x25mm 12VDC 0.25A 4-Wire Fan

Description

Protechnic MGT9212HR-W25B 92 x 92 x 25 mm 12 VDC 0.25 A 52.5 CFM axial cooling fan. This unit features a high-performance dual ball bearing system housed within a glass-fiber reinforced PBT plastic frame and 7-blade impeller, both rated UL 94V-0 for flame retardancy. The brushless DC motor incorporates a 4-wire interface supporting pulse width modulation (PWM) for variable speed control and a frequency generator (FG) signal for tachometer monitoring. The mechanical design is optimized for high static pressure and long-term operational stability in vertical or horizontal orientations.
